Door aligning and cushioning device



Oct. 27, 1931. J. sWANsKl DOOR ALIGNING AND CUSHIONING DEVICE Filed April 23. 1930 NNN JL Af Patented ct. i931 STATES JOSEPH SWANSKI, OF WORCESTER, MASSACHUSETTS DOOR ALIGNING- AN D CUSHIONING DEVICE Application led April 23,

rIhis invention relates to an attachment for automobile or other doors, by which lost motion and rattling is effectively prevented.

It is the object of my invention to provide an improved device for such purposes which is simple in construction, economical to manufacture and reliable and effective in use.

An important feature of my invention relates to the provision of a resiliently mounted wedge-like member adapted to take up any lost motion which may develop after the door is closed and to eectively cushion the door.

My invention further relates to arrangements and combinations of parts which will 3 be hereinafter described and more particularly pointed out in the appended claim.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a sectional plan view of my invention;

Fig. 2 is an end view, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is a. plan view of the wedge shaped member and its support;

Fig. 4 is a side elevation of the parts shown in Fig. 3;

Fig. 5 is an end view, looking in the d1- rection of the arrow 5 in Fig. 4;

Fig. 6 is a plan view of the guiding member; and

Fig. 7 is a side elevation of the parts shown in Fig. 6.

Referring to the drawings, I have shown my invention as applied to a door D and corresponding casing C, the door having a swinging closing movement in the direction of the arrow a in Fig. 1. V

My invention comprises a base or support 10, a wedge-shaped member 12 slidably mounted on the base 10 and a cooperating guiding member 14. I have shown the base 10 as secured to the edge of the door D and the member 14 mounted in a recess in the edge of the casing C, but it will be understood that the parts may be reversed if desired, with the base 10 secured to the casing and the guiding member 14 secured to the door.

The base 10 is preferably formed of sheet metal secured in position by screws 15 and 1930. Serial No. 446,683.

having side portions thereof bent upward and inward as indicated at 16 to provide guideways for the wedge-shaped member 12.

The member 12 is grooved at the opposite sides, as indicated at 17, to receive the guideways 16. The member 12 is substantially semi-circular in cross section and forms in effect a segment of a cone. rlhe interior of the member 12 is provided with a recess 21, formed to receive a coil spring 22.

One end of the spring 22 engages the inner end 23 of the recess 21 and the other end of the spring is engaged by a lug 24 struck up from the base 10. The wedgeshaped member' 12 is thus secured from displacement relative to the base 10 and is resiliently pushed forward in the direction of the arrow Z) in Fig. 4. The guiding member 14 is formed with a segmental conical re` cess adapted to receive the wedge-shaped member 12 when the door is closed.

The member 14 is also provided with ears 31 to receive screws 32 by which it is secured in a correspondingly shaped recess 33 in the casing C.

'Ihe normal position of the member 12 on the base 10 is an extreme forward position, as indicated in Figs. 3 and 4. When the door is closed, however, the parts are so related that the wedge-shaped member 12 is forced backward a certain distance, coimpressing the spring 22.

It will be noted that the member 12 tapers both longitudinally and also transversely and exerts a cam action against the guiding member 14 by which the door will be raised or lowered as may be necessary to align the member 12 with the guiding member 14. After the door is closed, the spring 22 acts to press the wedge-shaped member 12 as far as possible into the guiding member 14, thus cushioning the door and taking up any lost motion which may develop during the progress of the automobile. This yielding follow-up action of the member 12 forms a very important and useful feature of my invention.

While I have shown and described my invention as particularly applied to an automobile door the utility of the invention is 2 e j i 1,829,462

not limited to such use but the invention is alsoapplicable to other doors and also to car or bus windows in which a similar relative motion of the parts occurs. e
